We reviewed 50 skin biopsies obtained from 40 patients with cutaneous leiomyoma during a 10 year period from January 1980 to December 1989. The result.s were summarized as follows: 1) Sex distribution showed a female preponderance with male.female ratio of 1: 1.9. 2) The age distribution was relatively even from childhood to old age. The mean age was 47,8 years, 3) The most common site of lesion was lower leg(34%) followed by hand(24%), foot(12% ), anterior chest(8% ), face(6% ), neck(4%), upper arm(4% ), labia major(2 %) and nipple(2%). 4) The lesions were relatively well circumscribed subcutaneous nodule, papule, plaque and nodule which measured between 0.3cm to 5cm in size and their colors were erythematous to light brown. 5) The most common clinical and histopathologic type was angioleiomyoma(75%) followed by solitary piloleiomyoma(12.5%), multiple piloleiomyoma(7,5%) and solitary genital leiomyoma(5% ). Angioleiomyomas were clincally associated with cavernous hemangioma, myoma of uterus and systemic lupus erythematosus. 7) The clinical diagnoses were mass(30% ), epidermal cyst(20%), dermatofibroma (12.5% ), leiomyoma(12,5%), neurilemmoma(5%), lipoma(5%), calcifying epithelioma(2.5%), metastatic carcinoma(2.5%), morphea(2.5% ), fibrocystic disease(2.5%), glomus tumor(2.5 % ) and Dupuytrens contracuture(2..5%).

Median raphe cyst is not a cornmon disease and represents a defect in the embryologic development of male genitalia. It occurs most commonly near the glans penis, but may occur anywhere from the urethral meatus to the anus, and is lined by entodermal or ectodermal epithelium. Surgical excision is the treatment of choice. Recently we observed a 29-year-old male patient who had had a typical median raphe cyst since childhood on the ventral aspect of the glans penis. On histological examination, the cyst was lined by stratified columnar epithelium varied from four to eight cells in thickness.

Primary Cutaneous Neuroendocrine Carcinoma(CNEC : or Merkel Cell Tumor) usually occurs as a solitary tumor in middle aged to elderly individuals. This tumor may occur on any layer of the skin but the most frequent location is in the dermis. Electron microscopic studies reveal that the tumor cell contains round, dense core granules similar to epidermal Merkel cell and other cells of the neural crest derived APUD system. We describe the clinical, histological, electron microscopic, immunohistochemical observation of a case of primary CNEC in a 66-year-old female and discuss the theories regarding the histogenesis of this unusual tumor.

In a previous communication, we described a relatively simpli. method for assaying quantities of sweat using the skin surface hydrometer. In order to evaluate the pharmacologic response of weat glands in psoriasis, vitiligo and loalized scleroderma, we measured the basal skin conductance and the quantity of sweat induced by intradermal injections of pilocarpine nitrate in the lesional and per ilesional skin. The results were as follows : 1. In psoriatic plaques, based skin surface hydration and the sweat response to pilocarpine was markedly reduced (p<0.05), but there were no significant differences in normal perilesional skin. 2. In generalized vitiligo, basal skin surface hydration and the sweat gland response was normal. In the case of the segmental type, there was a slightly decreased sweat response in the lesion but, not significant statistically. 3. In the morphea plaque, basal skin surface hydration and the sw.at response to pilocarpine was markedly reduced but was normal in perilesional skin. This study presents evidence of the functional changes in the development of sweat secretion and surface hydration in the lesions of psoriasis, morphec and segmental type of vitiligo. The demonstration of ahnormalities in the pharmacolopic response to pilocarpine induction led us to suggest the possibility that some degree of sweat gland involvement is induced by the pathogenetic mechanisms of these diseases.

We present a case of venous hemangioma which is seen beneath a clavus (corn) developed in the interdigital area of the foot. Clinically, a violaceous papule was located on the third and fourth interdigital spaces under an overlying corn. Histopathologic examination showed a non-encapsulated dermal mass composed of thick-walled and thin walled vessels lined by a single layer of endothelial cells. Some thick-walled vessels had protruding endothelial cells into the lumen and through Verhoeff-van Gieson and Masson-trichrome stain of the tissue section, we found that the vascular mass was composed of vein.
